Minyari Dome Project

Home » Minyari Dome Project

The 100%-owned Minyari Dome Project covers 877km2 and features the Minyari Dome geological structure which hosts multiple delineated deposits

In September 2024, an updated Minyari Dome Mineral Resource Estimate (MRE) was announced. The Minyari Dome combined Mineral Resource now contains 2.3 million ounces of gold, 84,000 tonnes of copper, 661,000 ounces of silver and 13,000 tonnes of cobalt.

In October 2024, the Company announced the key outcomes of the Scoping Study Update completed on the Minyari Dome Project. The Scoping Study identifies a potential stand-alone gold mining and processing operation at Minyari Dome. It presented the preliminary evaluation of such a development at Minyari Dome based on the September 2024 MRE. Key highlights of the Scoping Study included:

  • Initial combined open pit and underground mine schedule of 30.2 Mt at 1.5 g/t gold for 1.5 Moz gold.
  • Over 10 years of initial processing life with a nameplate throughput of 3 Mtpa.
  • Simple, non-refractory metallurgy allows for a standard Carbon-in-Leach (CIL) process plant, delivering an estimated gold recovery of 90%.
  • Total pre-production capital cost of A$306M, including A$90M for pre-production mining.
  • Forecast average All-In-Sustaining-Cost (AISC) of A$1,721/oz (equivalent to US$1,205/oz).
  • Pre-tax NPV7 of A$834M and 52% IRR, assuming US$2,100/oz gold and 0.70 A$/US$ (A$3,000/oz).
  • Post-tax NPV7 of A$598M and 46% IRR, assuming US$2,100/oz gold and 0.70 A$/US$ (A$3,000/oz).
  • Pre-tax NPV7 of A$1,696M and 91% IRR, assuming US$2,800/oz gold and 0.70 A$/US$ (A$4,000/oz).
  • Post-tax NPV7 of A$1,205M and 79% IRR, assuming US$2,800/oz gold and 0.70 A$/US$ (A$4,000/oz).
  • Payback period of approximately 2.0 years from the commencement of gold production.
  • Latent potential to further boost economics with resource upside and by-product opportunities.

Minyari Dome Project Location Map

The Paterson Province geological setting of the Minyari Dome deposits is Proterozoic-aged, predominantly meta-sediment hosted intrusion related vein, breccia and replacement style precious and/or base metal mineralisation. Local controls on mineralisation commonly involve variations in both the competency/hardness and chemical composition of rock units, in combination with other “discrete” structural and intrusion controls.

At the Minyari deposit during 2021 mineralisation was discovered immediately east, west, and both up plunge to the southeast and down plunge to the northwest, including significant high‐grade breccia style gold-copper mineralisation.

In February 2023, Antipa regained sole rights to the Tetris, Pacman and Pixel tenements and greenfield targets (previously part of the Wilki Farm-in Project with Newmont). Following the transaction, Antipa’s 100% controlled land holding in the Paterson Province was boosted to approximately 877km2 (previously 144km2).

KEY DEPOSITS

MINYARI

The Minyari deposit hosts a large gold-copper-silver-cobalt mineral system that extends over a 500m strike length and across a horizontal width of up to 300m. Mineralisation begins at surface and extends to depths of up to 670m and remains open in several directions. In 2024, mineralisation was discovered extending southeast from the eastern region of the deposit, and this new zone remains open along strike to the southeast and down dip. This zone may be evaluated with further drilling during the upcoming programme.

WACA

Mineralisation at WACA occurs along a 650m strike length with a horizontal width of up to 100m, extending from surface down to a depth of 510m. The deposit remains open in multiple directions, including down plunge, offering further upside for Resource extension.

GEO-01 & MINYARI NORTH

The maiden MREs for the GEO-01 (151koz gold) and Minyari North (20koz gold) deposits combine for 171koz gold and represent significant new discoveries of near surface mineralisation. These deposits are located between 300m and 600m of the Minyari or WACA deposits. GEO-01, in particular, shows significant zones of thick, near surface, potentially open pittable, gold mineralisation, some of which are high-grade. Multiple zones of mineralisation at GEO-01 remain open, with large areas to be tested for additional strike and depth extensions as part of the upcoming drilling programme.
